Patent number: 11698330Abstract: The present disclosure is directed to rheometric fixtures for making rheological measurements of yield stress fluids. In some embodiments, the fixture can be an improvement of a typical vane by having the ability to create a more homogeneous shear profile in a test material, e.g., a yield stress fluid. These vane fixtures having fractal-like cross-sectional structures enable robust rheological measurements of the properties of yield stress fluids due to several outer contact edges that lead to increased kinematic homogeneity at the point of yielding and beyond. The branching structure of the fractal-like fixtures can alter the shape of a wetted perimeter of the fixture while minimizing an area thereof to allow the fixture to be inserted into fluids with less disturbance. In some embodiments, a cup with a ribbed inner surface can be used to hold the sample fluid and disassembles for ease of cleaning following completion of the measurement.Type: GrantFiled: October 15, 2020Date of Patent: July 11, 2023Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Crystal Elaine Owens, Gareth H. McKinley, Anastasios John Hart

Patent number: 11564877Abstract: Cosmetic compositions, systems and methods for conferring responsive durable shaping of keratinous fibers employ at least one shape memory polymer that includes a four-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups. The shape memory polymer forms a crosslinked network coating on a substrate, for example a substrate selected from keratinous substrates, for example, hair. Hair coated with the shape memory polymer and treated with an oxidizing agent can be shaped, locked into shape, and reprogrammed by modulation of pH. The coated hair retains durable shaping properties through at least one shampoo treatment. The cosmetic compositions, systems and methods provide durable and reprogrammable durable shaping of the keratinous substrate, for example for styling hair.Type: GrantFiled: October 11, 2019Date of Patent: January 31, 2023Assignee: L'OREALInventors: Samiul Amin, Niels Holten-Andersen, Bavand Keshavarz, Gareth H.

Patent number: 10478802Abstract: Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiO2 nanostructured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.Type: GrantFiled: May 9, 2014Date of Patent: November 19, 2019Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Robert E.

Publication number: 20170200966Abstract: The present invention generally relates to energy storage devices, and to metal sulfide energy storage devices in particular. Some aspects of the invention relate to energy storage devices comprising at least one flowable electrode, wherein the flowable electrode comprises an electroactive metal sulfide material suspended and/or dissolved in a carrier fluid. In some embodiments, the flowable electrode further comprises a plurality of electronically conductive particles suspended and/or dissolved in the carrier fluid, wherein the electronically conductive particles form a percolating conductive network. An energy storage device comprising a flowable electrode comprising a metal sulfide electroactive material and a percolating conductive network may advantageously exhibit, upon reversible cycling, higher energy densities and specific capacities than conventional energy storage devices.Type: ApplicationFiled: December 21, 2016Publication date: July 13, 2017Applicant: Massachusetts Institute of TechnologyInventors: Yet-Ming Chiang, William Henry Woodford, Frank Y.
